Description
The 321 Stainless Steel Hex Thick Nut, manufactured in accordance with the GB6175 standard, is a heavy-duty hexagon nut designed for applications requiring enhanced strength, thermal stability, and long-term reliability. Produced from 321 stainless steel, this nut is stabilized with titanium, which significantly improves resistance to intergranular corrosion and oxidation at elevated temperatures.
Compared with standard hexagon nuts, the GB6175 Hex Thick Nut features increased thickness, providing greater load-bearing capacity and improved resistance to loosening under high stress, vibration, or thermal cycling. Precision-cut internal threads ensure consistent engagement with mating bolts or studs, delivering secure and uniform clamping force. This fastener is particularly well-suited for aerospace, petrochemical, chemical processing, power generation, and oil & gas applications, where both high temperature resistance and corrosion protection are critical.
Features & Benefits
- High Temperature and Corrosion Resistance: Made from 321 stainless steel, this nut offers strong corrosion resistance in organic and inorganic acids at different temperatures. It is specifically designed for high-temperature and welded environments.
- Robust Construction: Made from 321 stainless steel, offering high hardness, toughness, and resistance to deformation.
- Secure Fastening: The nut has a standard hexagonal shape and is considered a standard part. This design ensures that it is not easy to slip when locked. The deep screw thread provides uniform force.
- Heavy-Duty Performance: Its increased thickness, conforming to the GB6175 standard, ensures superior mechanical integrity.

FAQ:
Q1: What makes 321 stainless steel better for this Hex Thick Nut?
A: 321 stainless steel is chosen for its superior resistance to heat, oxidation, and corrosion, particularly in environments where high-temperature stability and acid resistance are required.
Q2: Why choose a "thick" nut (GB6175) over a standard one?
A: The increased thickness provided by the GB6175 standard offers improved load-bearing performance and greater mechanical integrity, which is essential for high-stress applications.
Q3:Is this nut suitable for high-temperature applications?
A: Yes. The titanium-stabilized 321 stainless steel makes this hex thick nut ideal for continuous service at elevated temperatures.
Q4: Is this nut suitable for aerospace applications?
A: Yes. The 321 Stainless Steel Hex Thick Nut is ideal for aerospace, as well as chemical processing and oil & gas industries, due to its durability and reliability in extreme conditions.
Q5: Does the design prevent the nut from slipping?
A: Absolutely. The standard hexagonal shape combined with deep, precision threading ensures uniform force application and a secure fit that is not easy to slip when locked.
